Claims. (01.16745) This invention relates particularly to a means for coloring and therapeutic treatment of skin, lips and hair by means of suspensions of water insoluble inert finely divided coloring matter in carbohydrate materials. v v

' Certain sugars, notably sucrose, have relatively high antiseptic powers and havebeen employed for a long-period of time for food preservation.

It hasbeen found thatthis antiseptic property, particularly when combined with other antiseptics'. notably boric acid, is also useful on the skin, lips'and scalpwhen thin illm'sioi the material of my invention have been applied i i-the treatment of mild infections such" as e}: I impetigo, dermatitis, and seborrhea'.; when iat ",jleast finely divided sulphur is suspendedin 1 these films the material has beenxfoundgiurther ,jeflicacious in. the treatment of scabies and also w; -certainacneconditions.

In the priorart, cosmetic coloring matter and. therapeutic agents have depended for-their a'd- .herence to skin. surfaces, to mucous membranes, and to hair shafts, either by theadherent power of a greasy base materiaL'or by the roughnessi .oi the or by their inherent ability-tethering will adhere to the skin surfaces withoutgtheuse of grease, which will not'ruliofii withordinary friction and which will notfii 'ariyway'stairi the? body tissues.

Hair, lips, and skin coated with emissions my invention seem to take on a' muchv more natural appearance than when coatedwith products of the prior art and my material is also nonstaining. The products of my invention do not come 01! with ordinary friction. .Lips coated with my material when dry, donot smear if rubbed, as they do with greasy lipstick.

It is not the purpose of this invention to limit 10 the manner of preparation of the material, as it maybe made according to various formulae now employed in preparation of candy and other carbohydrate materials with the exception that my preparation. contains a suspension of water insoluble materials therein.

one-or the means of dispensing the material oiof my invention is from the surface coating on a container containing water and applicator as described in my co-pending pa'tentap'plication No. 287,449 applied for"*July-3l, 1939, entitled y invention is on applicators or on combs'which :may be moistened with water for application'to' a tissues to be colored as described in c o-peini-.; 1

ing patent app ication Serial No. 233;648'entitled 50 "Applicators for plastic coatings, filed July- 10a 1939, Another means of dispensing tl ematerial Containers." Another means of dispensing is in containers containing a hardened cake of the material of my invention from which the desired amount of the coloring material is removed and applied by use of a moistened brush. This last method has been found to be particularly useful for coating hair in the manner now employed for dyeing hair. It has been found that after coloring hair in this manner the application of an oil, particularly mineral oil, tends to fix the coloring material on the surface so that it is less liable to be rubbed off on friction.

A convenient formula for use in connection with the last mentioned method of applying my coloring material which required very little moistening to obtain the desired amount of coloring material, was prepared as follows: 4 parts sucrose, either with or with 2 parts water, were heated to melting and to this was added about 1% parts by volume finely divided pigment ma terial, part boric acid, and part protein (either gelatin or zein) which was stirred thoroughly and the resultant product poured out to cool and harden in suitable dispensing containers, or applicators coated therewith. Another formula found useful for this purpose contained the above ingredients prepared as described with one-fourth part of sulphonated castor oil added to the material while still in the liquid form. Larger amounts of sulphonated oil tended to make the product soft and even-semiliquid when cooled. This fiuid material which would not'harden and was not useful as a coating material proved to be an excellent scaleremover in the scalp and had a lasting beneficial efiect on seborrhea or dandrufh' Protein materials in the form of zein (vegetable protein) or gelatin (animal protein) were perhaps somewhat decreased water solubility.

However, when as much as 20% or more, and particularly when as much as 50% by volume of protein in the form of gelatin was added to molten sugar, entirely different results occurred. To introduce gelatin into the molten sugar ma terial it was necessary first to let the dry gelatin absorb an equal volume of water before adding or it would not go into solution with the molten sugar material. The product resulting vfrom the admixture of hydrated gelatin of this type in a quantity upwards of 20% by volume to molten sucrose had the appearance and general. properties of Indiarubber. Kneading and heating the material increased the elasticity and flexibility of the product which elastic properties did not disappear on cooling or allowing to stand for a period of time involving a number of weeks. These rubber-like properties were further enhanced by the addition of at least 1% triacetin added in amounts up to 10% by volume to melted and/or triethylene glycol, di 2 ethylbutyrate, dibutyl phthalate, dimethyl phthalate, or other cellulose ester plasticizer, in an organic solvent such as acetone. Sulphonated castor oil in an appreciable amount, for example 10% by volume added just after having added the hydrated gelatin to the molten sucrose and continuing heating. and stirring also tended to further enhance these properties. Such materials containing 20% and upwards of finely divided zinc oxide and/or charcoal, did not seem to have any of their rubber-like properties impaired. Heating molten sulphur with the final product seemed to increase its hardness and decrease its water form selected from the group consisting of su-v crose, lactose, dextrose and maltose, which contains protein material selected from the group consisting of zein and gelatin, and at least 10% 'water insoluble pigment material.
